Often the term hemangioma is used loosely to describe all vascular lesions, when in fact a true hemangioma is most likely not what you have. "Liver Hemangioma" is actually not a hemangioma, but should be referred to as a venous malformation. Most often they are not found in adults until over age 40 and often because something else was going on and the lesion just happened to be found...not because it had been the route of any problems. They are usually found by a routine ultrasound or CAT scan and present no symptoms to the patient. Sometimes patients will have stomach pain, vomiting, anemia or a low platelet count. The only significant risk ,which is very uncommon is that the lesion ruptures and bleeds...might be caused by trauma, (car accident) or pregnancy. These lesions are benign and require no therapy unless they are very large or pregnancy is likely. If there is a need to excised the lesion, it can be done safely by an experienced liver surgeon familiar with liver venous malformations. More often medical monitoring is recommeneded, follow up ultrasound and or CAT scan to track changes.
